Years ago (pre-COVID) I was visiting a friend in Niagara Falls NY and we took the walking bridge into Canada for a nice night out. (I was born in Canada but moved to the US as a child.) On the way back, a young customs agent asked me at the border back into the US “Where were you born?” I say “Canada.” He then asks “How long will you be visiting the US?” I reply “I live here.” I had recently gotten married so when he went to look me up on the computer, my name wasn’t found. And neither was my maiden name! He then asked me for my green card, to which I responded that I’m a US citizen who was naturalized, and he didn’t believe me! I told him I can prove it, my mother is American. Then he looked HER up, and couldn’t find her either! Mum has been married three times and after being detained for almost two hours we finally discovered that in the citizenship database, they have her listed not under her birth name, or her current married name, or even her first husband’s name, but under the last name of my father (husband 2). It might not seem very harrowing, but for two solid hours, I was terrified that they weren’t going to let me back in!
